To provide a transparent compact fluid pump capable of easily confirming the inside thereof and being efficiently refilled by allowing the content of the pump to be discharged through a nozzle when a flexible pressure member is pressed and allowing a specified amount of new substance to be flown into a formed chamber when the flexible pressure member is released from a pressure.
A first connector 52 is installed on a storing device, and allows fluid to pass through thereof. Also, a flexible dome 60 is formed of a semi- spherical flexible substance, and intended to be transparent so that the presence of soap in a pump 50 is visible from the outside. When a lever is operated, the pressure member 60 is pressed down toward a base 51. A pressure caused by this movement can push in a ball 70, open a ball 80 against the force of a spring 81, and distribute the soap. In addition when the pressure member 60 is released from a pressure, the member is returned to the original position due to its flexibility, and a pressure inside a chamber 90 is reduced, the ball 80 is pushed in, and the ball 70 is opened. Thus, the pump chamber 90 can be refilled.
